Queries frequency stats in Redis?

In my application I am implementing a server-side cache using Redis (for mySQL database). When data change in the database, I want to completely clear the cache to invalidate the old data.

However, I would like to see some statistics about how often are different keys queried in Redis, so that I can sort of manually pre-fetch frequently queried data for them to be available immediately after clearing the cache.

Is there any way how to see these statistics directly in Redis? Or what is a common solution to this problem?

redis-cli --hotkeys can do the help for redis-cli version 4.x and above.

You can use the object command.

OBJECT FREQ returns the logarithmic access frequency counter of the object stored at the specified key. This subcommand is available when maxmemory-policy is set to an LFU policy.
